works as well :) I don't like those kinds of things for this purpose
because it takes longer for people new to the code to read and
understand it than, say
,----
| (boolean) $string;
`----
(which in my case does a pretty meaningless conversion)

If you are worried that it takes longer for people new to the code to
read and understand then add comments! If it is about readability then
give them something to read. You could even create a function that is
more readable than the 'if' alone;
$foo = booleanString($string);
